Some help on IH history and CIH

I know IH sadly went out in 1985 and became CIH which I guess kept IH and today the Farmall name alive. I always seem to get in arguements over IH and CIH but I thought I read at one time that IH already had the magnums, 7110,7120,etc. on the drawing board around 1983 and they were patterened off the 5288's and 5488's redesigning the 18 speed trans. and making it a full power shift but a union strike and bad farm economy set IH back. Also, is it true tenneco did not want IH tractors just Case tractors and IH equip. and the IH rotor combine untill farmers did not want case tractors and tenneco bought the magnum plans and put a redesign cummins motor in them to help save the company?

I doubt if any one person knows the whole story. At the dealership , we found out one Dec morning in 1984 I believe, it was a notice on the computer that Tenaco was buying IH. Boss came back into shop and told me when I came in to work. It didn't become official until sometime early in 95 as it had to pass the gov't monopoly rulings. When it came time for dealer to sign his new franchise agreement boss was in Florida for the winter months so I actually signed it for him. Case pretty much called the shots but I think they heard a lot of feed back they immediately did some compromising. I remember one thing Case told dealers, we will never build an articulated 4-wheel drive. Well, didn't take long for that to change. When they showed dealers new machines would be red that made a lot of IH dealers happy. Far as the magnum, I attended one of the early service schools at Racine on the Magnum and a lot of the people were from the Case side of the merger as they called it. They kind of went over which side contributed to particular items on the tractor. Not a lot was discussed as to what had been in the works previously. We did get the impression though that the Case designed line of tractors had probably reached the point where they needed major changes to meet the competition so I think they were just as interested in getting the basic tractor design from IH as they were the Combine and rest of the implements. Otheres certainly know a lot more than I do about this as I was a mechanic, not involved in the inner workings of the co. It was really hard to swallow though, still is.

The link probably does not answer your question and gets off the subject some, but you might read it. It is "pinned" on the Red Power Forum, and has been added to since January 2009. I for one have not heard about the particular "rumors" you listed. There are a lot more about the merger.
CaseIH

The MAGNUM is based largely off of the next generation IH tractor that was already in the works. CASE had its own new series they were working on too, but it was dropped.

When Tenneco bought the IH Ag Division and mmixed it with CASE (which they wholly owned) they wanted the new tractor, Axial Flow combine and the dealer network.

The CASE dealer network was poor, (at best) with few locations nationwide (and worldwide) compared to IH.

After the merger, the CASE tractors were kept in the line for 2-3 years until the MAGNUM could be fully developed. TENNECO did not buy the FARMALL plant in Rock Island, IL where the IH tractors were made. They needed to have something to sell, so they bridged the gap with re-painted CASE tractors.
